Q:"How does the Nite-Guard work? How many do I need to protect my yard from raccoons? Do I need to mount them differently for deer?" Thanks. George

Answer: The Nite-Guard Solar is a new addition to animal control products. Solar powered, each Nite-Guard light flashes a red light on and off from dusk to dawn. Scientific research shows that night animals flee when they see the red flashing light as they fear they have been discovered or are being watched. This completely weatherproof animal pest repeller works best if used in multiples of at least 4 units. Otherwise the animal most likely will enter your yard or property from a direction away from the flashing red. Each light mounts to flash in only one direction with an approximate 30 degree angle of sight as one moves right or left away from it. This is why multiple units are needed and spacing between lights is needed as well.

If mounted high, the light can be seen for a long distance, depending on the lay of the land. A flat, open area with four Nite Guards placed at 10’ for owls will protect an area 1/2 mile in each direction. Even at 3 feet off the ground a range of several hundred yards' protection is common. A night predator stops the instant he sees the flash. So mount lights according to what you want to keep away. Deer will respond to higher lights than bobcats, raccoons, etc.

For small predators, these are the manufacturer's installation instructions:

For predators like raccoon, opossum and skunk; put lights approximately 25 feet apart, around your entire perimeter (all four sides of the area) and place them eye level to the predators approximately 10-12 inches off the ground. If the area has sides longer than 50 feet, more lights should be used on each side. Face lights outward from protected area.

For deer, these are the installation instructions:

1. Four Nite Guard lights placed on a single stake 4 feet high, each light facing a different direction. Moving the Nite Guard lights and stake every 7 to 10 days is absolutely critical as it breaks the pattern that deer may get used to. You do not have to move them far, 20 or 30 feet is fine, more is better. If you do not move the post with the lights around the deer will begin to “pattern” them in the exact position night after night, thusly losing fear of the flash.

NOTE: Deer are perhaps the most destructive nocturnal animal in modern times, they are also the most intelligent. Deer are very hard to deter from an area and, with the exception of the Nite Guard, will ignore most attempts to stop them from getting at the food that they want. The also act differently than a predator type animal and so we need to approach the placement of the lights differently.

2. You could also use a perimeter type placement against deer, placing lights 100 feet apart and approx. 4 feet high. Again, you will need to move the lights around every 3-10 days to break the pattern. Suggestion: Use the Nite Guard in conjunction with some of the other “weapons” they may already have in their “arsenal” against deer. Most people with deer problems are very well away of the deer’s intelligence and know that they get used to things easily. Use the Nite Guard lights along with some type of “repellant spray”. The deer then will not only “see” the predator (the flash of the light), but they will also “smell” the predator. This can be a very powerful deterrent for those deer that seem impossible to repel. You will be able to outsmart deer and protect your gardens and crops with the Nite Guards!
